Billwojo, you forgot the motor which is directly connected to the plater in an idler drive. It does not have a bearing? Actually, it has two, one on either side of the stator. I’m sure it is a cool device.

Billwojo is a machinist, I’m a retired HD master mechanic.
WE can make anything quiet. If you’re nice WE might teach you a thing or two..
If not WE’LL leave the 100 years between us to someone that DOES.
The only TT I can’t get quiet are the old mechanical automatics. Like a Zero 100. (sure nice looking for being such a pile SQ wise) A TD224 I can get to work perfect and be quiet.
No matter what anyone builds, the platter can’t ride on a ball. Once you accept that, you will understand what QUIET is..
Air ride or mag lift is QUIET.. Everything else has rumble
The 33.3 BS being spouted is hogwash.. I know for a fact no one could tell the difference if I set it at 32.3 or 33.3 rpms, much less being or staying accurate. You might notice wow, BUT I haven’t heard that in 35 years, and even then more so on RtR tapes needing to be re-tensioned.
Startup on a rim drive is 1/4 to 1/2 turn to full speed.. The real way to Que is to TURN OFF the motor on a Russco and flip the switch to start the qued record.. Mine are full speed in 1/4-1/2 turn.. Summer/Winter (temperature change) They have GEAR SHIFTERS for Gods sakes, how cool is that... Remind me of Cylons, just need a JBL diffuser for a helmet..
So many goodies but only so much time. :-)
